802 MOSQUITOES OF NORTH AMERICA 



mentor, both species have been confused with Aedes serratus by Coquillett, 

 Theobald and others. All three species are very distinct in larval characters. 

 The coloration of the adults shows some variation.

 Culex bracteatus Theobald, Mon. Culic, v, 612, 1910. 



Original Description of Culex bracteatus: 



Near confirmatus, but the patch of scales on median portion of anterior half of 

 the mesonotum is golden brown, instead of whitish. Proboscis and palpi brown- 

 scaled, occiput brassy-yellow-scaled and with a patch of brown ones on each side. 

 Scales in middle of anterior two-thirds of the mesonotum golden brown, those along 

 the sides and on posterior third of the mesonotum deep brown, the latter intermixed 

 with brassy-yellow ones. Abdomen black-scaled, a narrow band of whitish ones 

 at base of each segment, expanded into lateral spots on the last three segments, 

 venter whitish-scaled, the black of the dorsum encroaching on the hind angles of 

 the first five segments. Legs black-scaled, the bases and large portion of the under- 

 side whitish-scaled; claws of front and middle tarsi toothed, those of the hind ones 

 simple. Scales of wings brown. Length 3.5 mm. 



Habana, Cuba. Four females collected by Mr. J. R. Taylor. 



Type. No. 7753, U, S. National Museum. 



Original Description of Aedes habanicus: 



Antennae rather small with the tuft at the middle; head hairs single; body 

 coarsely hairy; lateral hairs mostly lost, but two are present on the sixth abdominal 

 segment; air tube two-and-a-half times as long as wide, the pecten reaching to the 

 middle, followed by the hair tuft; anal segment broadly ringed by the plate; anal 

 gills short, about as long as the segment. 



Havana, Cuba, Oct. 28, 1903, from Mr. John R. Taylor, labelled "Culex con- 

 firmatus Arrib." we do not know on whose authority. They were associated with 

 many PsoropJiora ciliata, and doubtless came from some temporary pool or swamp. 



The following' is an abstract of the table : 



1. Air tube with the tuft beyond the pecten 8 



8. Pecten of the air tube with evenly spaced teeth 13 



13. Comb scales more numerous to many in a patch 21 



21. Anal segment ringed by the plate 22 



22. Air tube twice as long as wide or less, pecten of 12-14 teeth 26 



26. Scales of comb evenly spinulated, without central thorn 27 



27. Body pilose 28 



28. Pecten scarcely over half of tube; tuft normal 29 



29. Lateral hairs double or in threes on these segments 30 



30. Anal segment moderate with broad ring habanicus 



Description op Female and Larva of Aedes bracteatus (Male Unknown) : 



Female. Proboscis rather long and slender, subcylindrical ; labellse conically 

 tapered; vestiture black; setse minute, curved, black, those on labellae more 

 prominently outstanding. Palpi short, about one-fifth as long as the proboscis, 

 clothed with black scales and moderate, stiff bristles. Antennae filiform, the 

 joints subequal, rugose, pilose, black, second joint slightly swollen beyond 

 middle, yellow at base ; tori subspherical, with a cup-shaped apical excavation, 

 luteous, blackish and with a patch of fine black hairs on inner side; hairs of 

 whorls moderate, sparse, black. Clypeus rounded triangular, convex, black, 

 nude. Eyes black. Occiput black, clothed with broad, flat, dull white scales, 

 a narrow median line of narrow curved, silvery yellow scales on the vertex and 

 similar ones along margins of eyes, a diffused black patch on the sides close to 

 eye-margin, many erect forked pale yellow scales on the nape; bristles along
